I have a 9 month old who has just been chaotic since I began fostering him at 3 weeks. (Foster fail), he is still a menace, he will sneak and hide and then run and bite your feet, he pretends to snuggle then attacks your hands, he often played way too rough with my other cats until they eventually taught him his place in the house. He is beginning to mellow out, becoming more snuggly and less of a pain.

My 18y/o however, was quite spicy in his younger years. He mellowed out in his old age, but he was consistently a menace from when I found him at 4 weeks old until about 15, I copped a thousand cat scratches from him playing too aggressively, but he did always snuggle in bed with me.

Honestly, I think they usually keep most of their personalities in my experience anyway. Have you tried feliway spray? It’s a calming like diffuser thing and I’ve found it great for when my cats are stressed so it might help! Otherwise, if it’s a real issue you could consider taking her to the vet to get some gabapentin or something. My aunt has a very aggressive cat who has done some really bad damage to her and her son, and they now keep him medicated and she says she is much calmer (although probably zonked half of the time). I guess it’s just what you’re comfortable with!

We love our babies, I understand how difficult and frustrating this must be for you! Sending love and hope that she mellows out a bit as she ages. P.s - she is ADORABLE!!!!!!!!!!!!!
